ROBERT SKENE, OF LOUISVILLE, KENTUCKY.

INHALER.

SJPILCIFECATION forming part of Letters Patent No. 302,949, dated August5, 1884.

Application filed July 10, 1883. (No model.)

To all whom it may concern:

Be it known that 1, ROBERT SKENE, a citizen of the United States,residing at Louisville, in the county of Jefferson and State ofKentucky, have invented a certain new and useful Improvement in MedicalVapor-In halers; and I dohereby declare that the following is a full,clear, and exact description of the construction and operation of thesame, reference being had to the accompanying drawings, forming part ofthis specification.

The present invention relates to a device for inhaling medicated vapors,which can be easily applied to the face of the patient and worn withcomfort, provision being made for the attachment of or theinterchangeable use of different sized receptacles for the medicatedfluid, and means being furthermore provided for collecting the saliva orcondensed breath of the patient.

To these ends the invention consists in the construction and combinationof parts, which will be more fully described hereinafter, and then setforth in the claims.

In the drawings, Figure 1 is a perspective view of an inhaler embodyingmy improvements. Fig. 2 is a vertical section ofthesame. Fig. 8 is adetail view of a detachable perforated cap adapted to receive a spongesaturated with a medicated liquid. Fig. at is a detail perspective viewof another form of detachable cap for the purpose of inhalingchloroform. Fig. 5 is a sectional view of said chloroformcap, showingits front valve opening and the sponge-receptacle. tive view of theinhaler, showing the chloro form-cap in position and representing moreclearly the saliva-receptacle with its stoppered end.

In the drawings, A represents the shield or cover,which is made of metalof the form shown in the drawings, and is so shaped as to fit closelyover the mouth and nose, with thelower end tern'iinating in aring-shaped extension, A which is closed on the inside with a permanentbottom plate, A*, located in front of the month,with the end projectingon the outside sufficient to receive the sponge cap G. A

curtain, 13, of india-rubber or other soft material, extends around theedge of the shield to prevent it from injuring the face and to render itair-tight.

Fig. 6 is another perspec-.

All of the above-named valves are made of india-rubber or other softmaterial, and of the form shown.

A curved cup or receptacle, G, following the contour of the under sideof the shield A, serves as a receptacle for the saliva or con densedbreath of the patient and communicates with the interior of the shieldby means of openings I. A piece of sponge, H, is placed over theseopenings, and serves as a medium for allowing the saliva and condensedbreath to percolate into the cup or receptacle, and preventing theliquid in the latter from flowing back into the shield. A stopper, 9,applied to the outer end of the saliva cup or receptacle, as is shown inFig. 6, serves to close the same, and can be removed for emptying theliquid contents of the cup.

J J are small strips of metal for holding the sponge H in its place, andK is a perforatedplate between the valve-openings IJE and the spongeR inthe cap, to prevent the sponge from obstructing the openings. G is thespongeeap, which is iitted on the ringshaped extension A ofthe shield A,and closes the lower end of the latter. The bottom or outer plate, N, ofthis attachable cap 0 is perforated with small holes, through which themedicated air or vapor is drawn into the shield by the act ofbreathing.- v

R is a flat piece of sponge in the bottom of the cap 0 for the purposeof holding the medicated fluid, the vapors of which are drawn into thelungs by the air drawn through said saturated sponge and. the perforatedplates by which it is held. '1 P are additional valves onthe sides ofthe shield A, that are covered with hinged metal plates V V, which maybe turned aside and the valves rendered operative when the valves F arean insufficient outlet for the discharge of the breath.

L L are metal springs for holdingthe device on the face; but other meansmay be resorted to for holding the inhaler in position.

In Figs. 4, 5, and 6 I have shown a spongecap or liquid-receiver, T,which is specially adapted for administering chloroform or otheranaesthetic agent inlarger quantities than can be administered by thesponge-cap O. This cap T is made of a shell-shaped body or cylinderhaving an opening in its end plate that is covered by an india-rubbcrvalve, WV, adapted to open in an inward direction. A sponge, R,saturated with the anzesthetic agent, is placed in the cap T and is heldaway from the valve W by the perforated plate K. It may be stated thatthis plate and likewise the plate K of the ring-shaped extension A aremade detachable. A stoppered opening, 0, in the top of the cap T servesfor the admission of the chloroform without requiring the removal of thecap T from the body of the inhaler.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

chamber, and provided with inhaling and ex! 7 I haling valves, and withan attachable and detachable cap or receptacle for the liquid to bevaporized, substantially as herein set forth.

2. An inhaler for medicated vapors, having an outer saliva-cupcommunicating with the interior of the inhaler-chamber, substantially asherein set forth.

3. An inhaler having bottom openings, and a sponge placed over the same,and an exterior saliva-cup or liquid-receptacle, substantially as hereinset forth.

ROBERT SKENE.
